Leap, and the net will appear.
If you're going through hell, keep going.
Do not weep do not wax indignant. Understand.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Wherever you are - be all there.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
